▎ 摘  要

NOVELTY - A hybrid material comprises a platinum-containing sulfur-doped graphene oxide comprising 80.55 wt.% carbon, 1.26 wt.% hydrogen, 14.47 wt.% oxygen, 1.72 wt.% sulfur and 2 wt.% platinum. USE - Hybrid material is used as anode in direct methanol fuel cell. ADVANTAGE - The hybrid material has excellent reproducibility and stability, and high catalytic activity of methanol oxidation reaction in alkaline medium. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the hybrid material, which involves ultrasonically dispersing 100 mg graphene oxide in 100 ml ethylene glycol for one hour, ultrasonically dispersing 160 mg sodium sulfide in the resultant suspension for 45 minutes, autoclaving resultant suspension at 180 degrees C for 12 hours, filtering resultant product, washing, freeze-drying, obtaining a sulfur-doped graphene oxide, dispersing 50 mg resultant product in 32 ml ethylene glycol, ultrasonically processing for 1 hour, adjusting pH to 10.5 with sodium hydroxide having concentration of 1 M, dispersing 112 mu L hexachloroplatinic acid having concentration of 0.095 M in resultant suspension, ultrasonically processing for 10 minutes, autoclaving resultant suspension at 180 degrees C for 8 hours, filtering resultant product, washing, and freeze-drying.
